Question

Write an equation of a line whose graph is parallel to the graph of y = 3x – 10

Answer 1

May I help?

Answer 2

yes you may 3mar

Answer 3

The form of line equation requires two inputs:
- the slope of the line (which could be gotten from the parallel line)
- a point on the line itself or the intersect position with y-axis.

Answer 4

How many input did you get?

Answer 5

i don't understand

Answer 6

you need the slope of the line + one point it passes through
\[\frac{ y-y_1 }{ x-x_1 }=m\]

Answer 7

or you need two points on the line:
\[\frac{ y_2-y_1 }{ x_2-x_1 }=\frac{ y-y_1 }{ x-x_1 }\]

Answer 8

or you need the slope + intersect with y-axis
\[y=mx+b\]
m: slope
b: intersection between y-axis and the line

Answer 9

The slope is easily calculated by the parallel line.
"Any two parallel lines have the same slope."
so the slope of the two lines is
\[m=3\]

Answer 10

We need now one more given in order to write the line equation.
